El sueldo bruto de un trabajador de la educación es de 900.000 pesos, si el descuento total que le harán corresponde al 20% de su sueldo ¿Cuánto será su sueldo líquido?
Answer:
Sueldo neto= $160.000
Step-by-step explanation:
Dada la siguiente información:
Sueldo bruto= $200.000
Descuento total= 20%
Para calcular el sueldo neto, debemos usar la siguiente formula:
Sueldo neto= sueldo bruto* (1 - porcentaje de descuento)
Sueldo neto= 200.000*( 1 - 0.2)
Sueldo neto= $160.000

Step-by-step explanation:
A triangle has sides with lengths of 40 yards, 75 yards, and 85 yards. Is it a right triangle?
Answer:
Yes
Step-by-step explanation:
To check, the squared values of the two smaller lengths must equal the squared value of the biggest length (Pythagorean Theorem)
40² + 75² = 85²
1600 + 5625 = or ≠ 7225
7225 = 7225
It is equivalent so it is correct.

Answer:
a) 6x² + 2x + 4
b) 32 cm
Step-by-step explanation:
a) In terms of x ,
Perimeter of the figure =
[tex](x+2) + (x^2) + (x^2) + (x+2) + (4x^2)[/tex]
[tex]= 6x^2+2x+4[/tex]
b) If x = 2cm ,
Perimeter of the figure [tex]= 6 \times (2)^2+2 \times (2)+4[/tex]
[tex]= 24 + 4 + 4[/tex]
[tex]= 32\;cm[/tex]
Aina builds a cube model out of manila cards. If the volume of the constructed cube is (2+3p) ³ cm³, find the total surface area of the cube in terms of p.
HELPPPP
Given:
The volume of a cube = [tex](2+3p)^3\ \text{cm}^3[/tex]
To find:
The total surface area of the cube in terms of p.
Solution:
Volume of a cube is:
[tex]V=a^3[/tex] ...(i)
Where, a is the side length.
It is given that,
[tex]V=(2+3p)^3\ \text{cm}^3[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]a=2+3p\text{ cm}[/tex]
Now, the total surface area of a cube is:
[tex]A=6a^2[/tex]
Where, a is the side length.
Putting [tex]a=2+3p[/tex], we get
[tex]A=6(2+3p)^2[/tex]
Therefore, the total surface area of the cube in terms of p is [tex]6(2+3p)^2\ \text{cm}^2[/tex].
Two turtles race. The speed of the first is 4 1/ 2 inches per minute and the speed of the other is 5 inches per minute How far apart the be in 3 minutes 5 minutes? 10 minutes?
Answer:
(a) 1.5 inches
(b) 2.5 inches
(c) 5 inches
Step-by-step explanation:
speed of first turtle = 4 1/2 inches per minute = 9/2 inches per minute
speed of the second turtle = 5inches per minute
distance = speed x time
(a) Distance traveled by first turtle in 3 minutes
s = 9/2 x 3 = 13.5 inches
distance traveled by second turtle in 3 minutes
s' = 5 x 3 = 15 inches
So, the gap is
s'- s = 15 - 13.5 = 1.5 inches
(b) Distance traveled by first turtle in 5 minutes
s = 9/2 x 5 = 22.5 inches
distance traveled by second turtle in 5 minutes
s' = 5 x 5 = 25 inches
So, the gap is
s'- s = 25 - 22.5 = 2.5 inches
(c) Distance traveled by first turtle in 10 minutes
s = 9/2 x 10 = 45 inches
distance traveled by second turtle in 10 minutes
s' = 5 x 10 = 50 inches
So, the gap is
s'- s = 50 - 45 = 5 inches
If ∝ and β are the roots of the quadratic equation x² – x – 2 = 0 then ∝² + β² is equal to
Answer:
α² + β² = 5
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a≠ 0 ) , then
sum of roots = - [tex]\frac{b}{a}[/tex]
product of roots = [tex]\frac{c}{a}[/tex]
x² - x - 2 = 0 ← is in standard form
with a = 1, b = - 1, c = - 2 , then
α + β = - [tex]\frac{-1}{1}[/tex] = 1
αβ = [tex]\frac{-2}{1}[/tex] = - 2
Using the identity
(α + β)² = α² + β² + 2αβ , then
α² + β² = (α + β)² - 2αβ = 1² - 2(- 2) = 1 + 4 = 5
[tex] \large \boxed{ \boxed{\mathrm{ \alpha }^{2} + { \beta }^{2} = 5}}[/tex]
Given : [tex] \alpha + \beta = 1[/tex][tex] \alpha \times \beta = - 2[/tex]let's solve for :

The thickness of 12 sheets of paper is 3.16mm. Find the thickness of 1 sheet
Answer:
79/300 mm
Step-by-step explanation:
We can use Ratio and Proportion to answer this question,
We know,
12 sheets of paper = 3.16mm
So,
1 = 3.16/12 mm
So, the thickness of 1 sheet of paper is => 3.16 / 12
=> 79/300
Hope it helps :)
Answer:
Step-by-step explanation:
Thickness of 1 sheet = thickness of 12 sheets ÷ number of sheets
= 3.16 ÷ 12
= 0.26 mm

A triangular prism whose total surface area = 64 cm2, and its lateral area = 40 cm2, find the area of its base?
Answer:
Area of its base = 12cm²
Step-by-step explanation:
The Area of its base = 1/2 of its surface area - 1/2 of its lateral area
Its surface area = 64, then 1/2 X 64 = 32cm²
Its lateral area = 40, then 1/2 X 40 = 20cm²
So, Area of its base = 32 - 20 = 12cm²
Chau will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an additional $0.19 per mile driven. The second plan has an initial fee of $57 and costs an additional $0.15 per mile driven.
Answer:
175 Miles has to be driven to do the plans cost the same.
Step-by-step explanation:
Assume The Chau Drive Y miles .
We Have Given Two Plans ,
First Plan = 50$ + 0.19$ × Y Second Plan = 57$ + 0.15$ × YNow,Put First Plan=Second Plan (When Both Plans Cost The Same)
50$ + 0.19$ × Y = 57$ + 0.15$ × Y
0.04$ × Y = 7 ⇔ Y = 175 Miles
How does the graph of
g(x) = 0.5(2)*-3 – 1
compare to the graph of
the parent function
f(x) = 2*?. Write a full
description.
Answer:
Here we have:
f(x) = 2^x
g(x) = 0.5*2^(x - 3) - 1
We want to compare g(x) and f(x).
The first thing we should do here, is to define the transformations used.
Vertical translation:
For a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
if N > 0, the translation is upwards
if N < 0, the translation is downwards.
Horizontal translation:
For a function f(x), a horizontal translation fo N units is written as:
g(x) = f(x + N)
if N > 0, the translation is to the left
if N < 0, the translation is to the right.
Vertical dilation:
For a general function f(x), a vertical dilation of scale factor k is written as:
g(x) = k*f(x).
Ok, now let's start with f(x), and try to use transformations to construct g(x).
We start with f(x).
If we start with a vertical dilation of scale factor k = 0.5, then:
g(x) = 0.5*f(x)
if now we apply a horizontal translation of 3 units to the right, we get:
g(x) = 0.5*f(x - 3)
if now we apply a vertical translation of 1 unit down, we get:
g(x) = 0.5*f(x - 3) - 1
Replacing by the actual function we get
g(x) = 0.5*2^(x - 3) - 1
So we got g(x).
Then, the graph of g(x) is the graph of f(x) dilated vertically by a scale factor of 0.5, then moved to the right 3 units, and then moved down one unit.

Which of the quadratic functions has the narrowest graph?
A. [tex]y=-2x^2[/tex]
B. [tex]y=\frac{1}{2} x^2[/tex]
C. [tex]y=\frac{1}{7} x^2[/tex]
D. [tex]y=-4x^2[/tex]
Answer:
C. y= 1/7x2
Step-by-step explanation:
The equation with the highest leading coefficient (the number before the x^2 term) will have the narrowest graph. Here, we have to choose between -1, 1/6, 2, and 1/8. The highest number out of all of those numbers is 2, so y = 2x^2 will have the narrowest graph.
Question # 2: A circle has a radius of 12 feet. What is the area of the circle? Use 3.14 for Pi.
Answer:
452.16 ft²
Step-by-step explanation:
Use the circle area formula, A = [tex]\pi[/tex]r²
Plug in 3.14 as pi and 12 as the radius, then solve:
A = (3.14)(12)²
A = (3.14)(144)
A = 452.16
So, the area of the circle is 452.16 ft²

Un cable guía de 600 pies esta sujeto a la parte superior de una torre de comunicaciones. Si el cable forma un ángulo de 65° con la Tierra. ¿Cuál es la altura de la torre de comunicaciones?
Answer:
La torre tiene 543.78 pies de altura.
Step-by-step explanation:
Podemos pensar en esta situación como si fuera un triángulo rectángulo, donde el cable es la hipotenusa y la torre es uno de los catetos. (Abajo se puede ver un dibujo de esta situación).
Nosotros queremos encontrar el valor de H, que es el cateto opuesto al ángulo conocido de 65°.
Entonces simplemente podemos usar la relación:
Sin(θ) = (cateto opuesto)/(hipotenusa)
donde:
cateto opuesto = H
θ = 65°
hipotenusa = 600 ft
sin(65°) = H/600ft
sin(65°)*600ft = H = 543.78 ft
La torre tiene 543.78 pies de altura.
Un frutero ha comprado 165kg de manzanas a 2 € el kilo; se le han estropeado 15 kg y el resto los vende a 4 € el kilo. ¿ Cuánto ha ganado? ( 1,25p)
Answer:
€270
Step-by-step explanation:
If a fruit vendor has bought 165kg of apples at € 2 per kilo, the total amount spent is expressed as;
Cost price = 165 * 2 = €330
If 15kg spoilt, the amount of fruit remaining will be 165 - 15 = 150kg
If he rests he sells for € 4 per kilo, then;
Selling price = 150 * 4 = €600
Amount earned = €600 - €330
Amount earned = €270
